Well, they could just update all tools and libraries to the versions used in FreeBSD 5. But the Finder has that really, really fast search feature. (beos like). I wonder how they are doing it. Just letting cron run updatedb wouldn't work, because you couldn't find a file you created 3 minutes ago. So I guess that they would have to have a new filesystem. Is UFS2 capable of this sort of thing?

What's also pretty cool is those little security features. Secure file deletion option (7 passes of random data), encrypted home folders, asking password after sleep, being able to lock the powermac g5 case,... Pretty cool that they are taking security seriously.
